STILE OR BARRIER.

To all who 12bit may concern: 7

Be it known that I, HIRAM A. DAVIS, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Stiles or Barriers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in stiles or barriers.

In the preferred form of this invention the desired results are obtained by using two barriers one controlled by the other. This controlling device comprises a link pivotally connected to a crank carried by one of the barriers and by a pin and slot connection to a crank carried by the other barrier, and a spring tending to hold the parts in a normal position with one of the barriers closed and the other in open position. By initially moving one barrier from closed position, the other barrier is moved from open to closed position by the crank and link connection. 011 reaching closed position the second barrier strikes a stop. Due, however, to the pin and slot connection, continued movement of the first barrier is permitted until it is released after the entrance to the inclosure when the parts are returned to their normal position by the spring,

The object of the invention is to provide a device of this type which is simple in construction, eflicient in operation and which elfectually controls the entrance therethrough so that but one person at a time may pass.

Referring to the drawings, Figure 1 is a plan view of a portion of a street car platform showing my invention applied thereto; Fig. 2 is a side elevation of the same; Fig. 3 is a view of the lever arrangement which connects the various gates of the stile; Fig. 4 is a similar view with the levers in a different position; Fig. 5 is a plan view of the means for compelling a sufficient movement of the stile; and Fig. 6 is a detail View of the same; and Fig. 7 is a detail perspective view of the cam and ratchet.

Specification of Letters Patent.

Application filed October 23, 1912.

Serial No. 727,372.-

Referring more particularly to the drawings, 1 represents the platform of a car upon which is mounted a vertical standard 2. The standard 2 extends from a base 8 and 1s provided with a bearing 4 on its upper end. Journaled in the base 3 and bearing t is a vertical shaft 5 to which a gate or barrier 6 is attached. When said gate or barrier 6 is in its normal position, as in Fig. 1, it lies in the path of passengers as they approach the interior of the car. passenger passes through, the said gate 6 is swung from the position shown in full lines to that shown in broken lines. This movement is accomplished by the passenger. The shaft 5 may be suitably connected to aregistering machine (not shown) by any of the well known means. When so connected,

a fare will be registered each time a pas-V senger swings the gate arm 6.

To prevent more than one passenger passing through the gate at a time, the following auxiliary gates are provided: Extending from base members 7 on the platform 1, are two standards 8 provided at their tops with bearings 9. Journaled in the members 7 and bearings 9 are two shafts 10 to which auxiliary gates 11 are attached. The gates 11 are adapted to be swung toward each other to close the passage. The said gates 11 are swung or operated when a passenger operates the main gate 6, and more than one person is thus prevented from passing through at a time.

The auxiliary gates 11 are actuated and controlled by the main gate 6 through the following means: Mounted on the lower portions of the shafts 10, below the platform of the car, are cranks 12 which are pivotally connected by a rod 18. The said cranks 12 lie on opposite sides of shafts 10, thereby permitting the gates 11 to move in unison in opposite directions. One of the shafts 10 is also provided with a crank 14: to which one end of'a rod 15 is pivotally connected. The other end 19 of said rod 15 is pivotally and slidingly connected to a crank 17 mounted on the lower end of the shaft 5, said crank 17 being provided with a slot 18. During the initial movement of the gate 6, and while it is moving to the position indicated by the line 21 in Fig. 4t, the crank 17 will actuate the rod 15, which will in turn rock the shafts 10 and close the auxiliary gates 11. The movement of the gates 11 may be Patented Feb. 3, 1M4.

\Vhen a limited by any well known means such as a pin or stop 22 adapted to engage one of the cranks 12. During the extended movement of the gate 6, the end 19 of the rod 15 will ride along the slot 18 thereby permitting the main gate 6 to have a free movement. It will be seen, that, by this arrangement, the auxiliary gates 11 will be closed before the main gate 6 is opened, thereby preventing more than one person passing through at a time. After a passenger has passed through and has released the gate 6, the said gate is returned to a normal or closed position by a spring 23 and may be held in said normal position, against the tension of the spring 23, by any means such as a pin 245 which is engaged by the crank 17. The spring 23 is connected to the rods 15 and 13 below the platform of the car and exerts an influence on said rods tending to close the main gate (3 and to open the auxiliary gates 11.

After the said main gate has been initially opened, it is prevented from being returned to a normal position until it has moved to a desired extent. This is accomplished by the following device: Mounted on the lower side of the crank 17 is a laterally and pivotally movable pawl 2% attached to a shaft 25 journaled in bearings 26. Surrounding said shaft 25 is a spring 27 which controls both the pivotal and lateral movement of the pawl 24. The pawl 24 is in operative relation with a ratchet 28 mounted on a semicircular member 29 having an offset 30. Mounted along one side of the member 30 is a cam 31 which lies below the ratchet 28. During the initial opening of the gate 6, the pawl 24: rides over the teeth of the ratchet 28 until it reaches the offset 30, when said pawl drops onto the cam 81. During the return movement of the gate 6, the said pawl rides along the cam 31 and when it reaches the offset 30 the said pawl is moved later ally out of the path of the ratchet 28. When said pawl is riding on the cam 31, it

is out of engagement with ratchet 28, and when it reaches the end of its return movement said pawl is elevated by the cam to a position to permit the spring 27 to move it laterally and to place the same in operative relation with the ratchet.

ll hile in the drawings I have shown the shafts 5 and 10 as supported by standards 2 and 8, I wish it to be understood that said shafts may be supported by any well known means such as the frame. of the car or any convenient parts of the structure on which the stile may be placed.

1 do not wish to limit myself to the precise arrangement and construction of parts shown and described, as it is obvious to those skilled in the art that these may be varied without departing from the essentials of the invention which in its broader sense comprises a multiple crank and lever system for operating inner and outer barriers controlling an entrance to a car.

I claim,

In a device of the type specified, a main gate, a slotted lever mounted on the pivot of the main gate, auxiliary gates, cranks mounted on the pivots of said auxiliary gates, a connecting rod between the cranks on said auxiliary gates, a second crank mounted on 7 5 the pivot of one of said auxiliary gates, a second connecting rod connecting said slotted lever with said last named crank, a stop for limiting the movement of said. gates, and a spring mounted between said connecting rods and adapted to return said gates to a normal position.

In testimony whereof I aflix my signature, in presence of two witnesses.
